Sure, give me a few hours. You’d speed up that process if I know in what country you live. That way I only have to loop through the cities in your country instead of the entire world. Or you could tell me your city.
I feel the issue you mentioned with the coordinates not representing the actual city centres heavily benefitted the US here. Looking at the image you showed for Tulsa, the downtown area isn't even shown. Milwaukee has Dineen Park in it which is 7km+ away from the city center. That's obviously not right as American suburbs are much more green than downtowns
I think the reason that the US dominated the list is because suburban communities are so common here (and an unfortunately large part of the culture); like you said, each house has its own yard and its own tree. It's funny how it's reflective of the individualist culture here -- how many people want their own picturesque home.
@themayonnaise most people in Europe live on the outskirts of these big cities (they are very expensive), and most of them have terrible transport and you need a car to go places there.
Yeah exactly. I live in Sydney, Australia and while I haven't been, I've had friends that have been to a number of those cities in the US and they've all said Sydney is way more leafy. It also has to do with density, the suburban spaces in the US are so huge that it skews the results, so the city centre can just be a concrete jungle if there's large enough suburbs. Meanwhile here in Sydney you can be in the CBD and have forested areas pocketed away. And generally here, people don't have lawns like they do in the US with one or two trees and that's it - my backyard has about 10 large trees and many more smaller trees and saplings.
Check out the neighborhoods of Ipanema and Leblon in Rio de Janeiro on google earth and street view . I haven’t find a place other big, dense city with so many trees and smaller plants in every street you go. 😍
The Netherlands has awarded a 'greenest city award' a couple of times to encourage municipalities to add greenary to their cities. Quite a nice initiative imo
How green a city doesn't only depend on how much plantation it has. A city with full of sprawling suburbs is actually bad for the environment. A city like Newyork even though it doesn't have much plantation is the best for environment and climate as a whole. Apartment buildings are lot more energy efficient because if their shared walls. A dense city like Newyork need much less asphalt per Capita. It needs much less piping and electric lines. People in a dense city can use metros and other public transportation which are inherently more efficient and easier to electrify. For example Newyork metro has been powered by electricity over a century now. Dense cities with apartments take much less land for the same amount of people than a sprawling city. We can give more land for nature by promoting dense urbanization. Newyorkers has one of the least CO2 per capita emissions in the whole USA.
The better way to do this would have been using the pre existing Normalized difference vegetation index that relies on infrared light reflectance of live plants, remote sensing data and satelittle views of this exists, and I would be interested in a comparison between the two.

from what I could tell, the main reason for northamerican suburbia to dominate the list is the quantity of clusters that are listed/counted because of single homes' lawns and their average one to three trees planted in the back; big city parks or general urban development with a denser presence of trees (typically seen in west/central europe, fe), when viewed from satellite imagery, tends to become big singular clusters. I also support the point that, although not being the purpose of the project (nothing wrong with it, it has its own value and significance), the "greenage" measuring does not necessarily correlate to quality of life or sustainable development, seeing as in these green-dominated american towns, it is strictly caused by inefficient land use, leaving a LOT of empty, practically dead grassy' space behind; this could be traced to many factors, but overall, poor modern city planning philosophy (suburbia), private property inequality, so to say, and, on top of it all, a heavy motormobile oriented infrastructure. My suggestion for a next vid, I might add, would be 'cities with the most uniform buildings', that possible? lol. Great video as always man, can't imagine the work that's been put it sometimes.
Maybe another reason why those US cities are so green is that they are inland? That means no area is taken up by beaches, port infrastructure, etc that generally isn't green. Would also explain why that Kazakh city is so high up the list.
Hey man! I wanted to make a comment on your previous video, but forgot to finish it, so I'm writing it here. Your analyses are very high quality, which is clearly seen by your eye for detail. Manually handling mismatches in specific instances (not even groups of instances) is a sign of a great data analyst, trust me - I know many analysts who just do basic macro-level data cleaning, run some measures and call it a day. Great to see that you are doing your projects with passion. As a network scientist, I have some topics for you that could be interesting to look into when you do your work: -network filtering: I recall in your previous video filtering cities by geographical radius; I think a worthy approach is to rather extract the so-called network backbone (this is typically for weighted networks, but can be run also on unweighted networks), you can filter it to any node/edge amount too. I know the disparity filter to be most common as choice. -network complexity: there are some entropy based measures for complexity, i.e. "minimum description length". The basic idea is a network is as complex, as many bits of information you need to reconstruct it - very structured cities would not be considered complex, e.g. grid structures. I know some algorithms, like the community detection algorithm Infomap or nested SBMs rely on this. Make a video where you detect communities in cities by network structure! That is called community detection in network science.
Yeah this is a case where the methodology is just not up to the task at hand. One obvious improvement is to weight the results according to population as right now you end up comparing US suburbia which is definitely very green but has very low density with cities that are way more dense. Nice effort though, keep up the good work.
It's much easier to separate vegetation in an image if you use multispectral imagery like Landsat/Sentinel - taking an image in thermal infrared easily seperates water, which shows up almost black. There are plenty of established tools like NDVI that are used in industry/science for this - you can also do intereseting things like track the water content of leaves over time, so identify fire-prone regions just from a satellite image (more water in leaves absorbs more infrared light). With enough data and some of the more interesting machine-learning tools, you can identify individual species of vegetation, but even with 'dumb' classification methods, it's simple to split forest from grassland/pasture.
wow very unexpected results, didn't expect us to have such green cities. You could have probably somehow crop the satellite footage to the city shape using shp files it would have been also easier to if you have used satellite imaginary in GeoTIF format
@@Amechaniaa then well the bigger the city, the more greens it got of course. If we just measure on the green pixels directly then cities like Chongqing would dominate the board since you can't even make out the urban area looking at it's border from above
@@haigiabaonguyen9299you could probably make it an average green instead of a total green, which would be more honest anyway regardless of using the borders or not
Yeah the “number of green clusters” condition introduces a sort of perverse incentive. I figure that SE USA pine forest cities are reading as one large cluster of green
Love your videos! Keep it up man. But could you upload your results somewhere? Sometimes I would really like to browse trough them but sadly there is no way
I have a question how can I calculate connection of roads like in last video. I downloaded qgis but I don't know how can I get most road intersection nodes count etc?
Aw dang,i wanted to make this 900+ long list but i realized that the ranking number was wrong,so even though i fixed the speed problem (by placing it at 0.25x) there was still possibly some cities that were skipped over unintentionally,massive apologies for anyone who wanted a full list,since i was really willing too :(

someone make list of these all cities in order by greenness so that i can find where my city is ranked
